So you are so smart that you know that when God told John to wright "first resurrection" He did not really mean first.
That in fact first really means several.
You do think highly of your self.
I think a different Greek word used means several .First means one.
I think I will take God's clearly stated facts in these verses.
First is first, is first, is first, is first
The promise is in respect to the first resurrection, is in respect to the eternal land typified by the temporal land, Israel here on earth. The promise of the first resurrection begins in Ezekiel.
Eze 37:12 Therefore prophesy and say unto them, Thus saith the Lord GOD; Behold, O my people, I will open your graves, and cause you to come up out of your graves, and bring you into the land of Israel. (Zion)
The fulfillment of the prophecy in respect to the first resurrection in Mathew below. .
Jesus, when he had cried again with a loud voice, yielded up the ghost. And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent; And the graves were opened; and many bodies of the saints which slept arose, Mat 27:50
The first resurrection began when Christ said; “it is finished”. The dead asleep in Christ, the Old testament saints that were in effect in a holding pen awaiting the trial of Christ came out of their graves and entered the new Jerusalem, witnessed by many angels Nothing could hold them any longer the payment in full was made. they dies trusting in Christ finished work just as we do. (no difference other than a matter of time. ) .
1Pe 1:11 Searching what, or what manner of time the Spirit of Christ which was in them did signify, when it testified beforehand the sufferings of Christ, and the glory that should follow.
Just as today to be absent of the body we enter the first resurrection as being absent of these bodies of death we are present in our souls with Christ as the beheaded souls under the altar fast asleep waiting for the second and final resurrection when the other dead in Christ ,that are alive reinging with Christ on earth.... in the twinkling of the eye both receive the second and final resurrection on the last day. New incorruptible bodies for all the dead in Christ while the rest (no faith) go up in smoke of God’s judgment never to come to new life, forever more. .
The one work of the second and final resurrection is done simultaneously in the twinkling of the eye. Then the saints (both) will receive their new incorruptible bodies in that one window of opportunity. The last day, the end of time.
